Disposable body fluid absorbent article having disposable securing means

Abstract

A disposal tape securing arrangement used to secure a disposable body fluid absorbent article such as a disposable diaper in a rolled up state for disposal includes an adhesive tape and a release tape. The adhesive tape is fixed at one end portion to the outer surface of the article and has an adhesive zone on the opposite end portion (i.e., free end portion). The release tape extends in alignment with the adhesive tape and has a release portion fixed to the outer surface of the article and a fold-back portion being contiguous to the release portion and folded back adjacent the end of the adhesive tape. The adhesive zone provided on the adhesive tape is releasably bonded to the release portion and the fold-back portion of the release tape is fixed to the inner surface of the free end portion of the adhesive tape.

What is claimed is:  
     
       1. A disposable body fluid absorbent article comprising an inner surface intended to be placed closely adjacent a wearer's skin, an outer surface intended to be placed remotely from the wearer's skin, an absorbent core disposed between said inner surface and outer surface, and disposal securing means for securing said article in a shape desired for disposal of said article, wherein: 
       said disposal securing means comprise a first tape and a second tape disposed between said first tape and the outer surface of said article and extending in alignment with said first tape;  
       said first tape has an inner surface and an outer surface and comprises a first fixed portion adhesively directly attached on the inner surface of said first tape to the outer surface of said article and a free portion comprising a tab zone located at an end of said first tape opposite an end thereof containing said first fixed portion and having no adhesive on both the inner and outer surfaces of said tab zone, and an adhesive zone between said tab zone and first fixed portion and having adhesive only on the inner surface of said first tape;  
       said second tape has an inner surface and an outer surface and comprises a second fixed portion extending from said free portion toward said first fixed portion of said first tape, said second fixed portion fixed on the inner surface of said second tape to the outer surface of said article and a fold-back portion being contiguous to said second fixed portion and folded back adjacent with and away from said first fixed portion of said first tape with said inner surface of said second tape facing outward toward said first tape to define an outward facing surface; and  
       wherein said adhesive zone provided on said free portion of said first tape is bonded to the outer surface of said second fixed portion of said second tape and said fold-back portion of said second tape is fixed on the outward facing surface of said fold-back portion to the inner surface of said free portion of said first tape.  
     
     
       2. The disposable body fluid absorbent article according to claim  1 , wherein said first tape comprises a discrete forward tape forming said tab zone and said adhesive zone of said free portion, a discrete backward tape forming said first fixed portion and a discrete intermediate tape having a forward end and a backward end and disposed between said forward and backward tapes and being elastically stretchable, said forward tape being fixed to the forward end of said intermediate tape, the backward end of said intermediate tape being fixedly held and directly attached to and between said backward tape and said fold-back portion of said second tape. 
     
     
       3. The disposable body fluid absorbent article according to claim  2 , wherein said intermediate tape is made of a material that will enable said intermediate tape to remain in a stretched state or elastically contract at least by a portion of elongation after said intermediate tape is released from tension following affixation to said absorbent article when soiled. 
     
     
       4. The disposable body fluid absorbent article according to claim  1 , wherein said first tape has a longitudinal axis and is folded in a Z-shape along its longitudinal axis so as to be unfolded longitudinally in actual use thereof and said adhesive zone provided on said free portion of said first tape is releasably bonded to the outer surface of said first tape. 
     
     
       5. The disposable body fluid absorbent article according to claim  1 , wherein said disposal securing means is provided in a center area of a rear waist region of said article. 
     
     
       6. The disposable body fluid absorbent article accroding to claim  5 , wherein said article is a pull-on diaper. 
     
     
       7. The disposable article according to claim  1 , wherein said first tape is a single piece of tape folded in a Z-shape defined by a top portion including said tab zone, an intermediate portion releasably bonded to a bottom surface of the top portion adjacent said tab zone, and a bottom portion functioning as a part of said free end portion of said first tape that is releasably bonded to the outer surface of said second tape with said adhesive zone and fixed directly to the fold back portion of said second tape.
